Introduction to the degumming process of the camera module

With the popularity of mobile phones, security cameras and other products, the camera industry has also developed vigorously. The camera module, the full name of the cameracompact module, can be abbreviated as ccm, and is an important electronic device for image capture. Today, we will learn about the process of removing glue from the camera module.


CCM consists of four major components: lens (lens), sensor (sensor), soft board (fpc), and image processing chip (dsp). Sensor is the core module of ccm, there are two widely used: one is widely used ccd (charge coupling) components; the other is cmos (complementary metal oxide conductor) devices.


In the production process of the camera module, a more important link is the bonding process of the camera, which will not only affect the assembly stability of the camera module, but also affect the lens yield during the finished product test. The dispensing process of the lens plays a crucial role in the subsequent product testing after the camera module is adjusted. Even if the quality of the camera module in the focusing process is relatively good, once the glue is improperly dispensed, it will affect the subsequent finished product testing, resulting in the camera module being unusable and scrapped.


Lens dispensing is increasingly pursuing a fast, high-strength, and easy-to-repair camera module bonding process. The selected lens dispensing adhesive is shadowless glue, which is usually referred to as UV glue. UV glue refers to a kind of adhesive that must be irradiated by ultraviolet light. It has a fast curing speed and can be converted from liquid to solid in a few seconds. It has an excellent bonding effect on plastics and various materials. Therefore, , is widely used. The fast curing and high bonding strength of UV glue are conducive to improving work efficiency and shortening the dispensing time. However, during the dispensing process, the glue often overflows and contaminates the surface of the product, which affects the quality of the product. The fast curing of UV glue makes it impossible for people to quickly react to the residual glue. The cured UV glue sticking to the surface of the product can only be removed by scraping with a knife. The knife scraping method not only requires the size of the product, but also The smaller it is, the harder it is to remove, and it may cause damage to the surface of the product, making it impossible to assemble the product.


After the focusing of the camera module is completed, UV glue needs to be applied to fix the lens, and then a finished product test will be carried out, and a batch of defective products will appear in the finished product test. Although there is no problem with the lens quality of these defective products, due to improper dispensing of UV glue, the glue overflows on the surface of the lens module, and the rapidly formed cured UV glue sticks to the petals and threads of the lens module. If a knife is used The method of scratching cannot penetrate into the inner surface of the petals and threads, which makes it more difficult to remove the cured UV glue, which affects the assembly and auto-focus function of the module in the finished product. Therefore, the lens module with excess UV glue cannot be reused. cause scrap. It not only increases the manufacturing cost of the product, but also wastes the production resources of the lens, which is not conducive to the development of the product. No matter how careful the dispensing operation is, it is difficult to avoid the generation of miscellaneous UV glue. How to effectively remove the cured UV glue and reduce the production cost is a major challenge for the majority of the industry.
